That’s what local militias look like.
At least they organized and cordoned their neighborhood. If anyone other than a cult did this in the US, the government would come down on them like a ton of bricks.
Cults are tolerated, with some exceptions (Waco’d David Koresh comes to mind).
You're more likely to get assistance. "I know where we can get explosives to reinforce the perimeter" or If you saw off that shotgun barrel it's more effective at close range" etc..
